AS TEMPERATURES soar across Wales, warnings have been issued about the dangers of swimming in reservoirs.

Welsh Water has produced a video, which was filmed at Pontsticill reservoir, highlighting the risks, such as submerged machinery and deep, ice-cold water.

The video features two teenagers who made a podcast in 2006 about the risks.

James Chappell and Adam Hale, both from Cardiff, recorded the original podcast about the risks of swimming at Pontsticill reservoir a month after a teenager died while swimming there.

It was part of a safety drive launched just before the school summer holidays.

The online film sees the pair cast as two friends who consider taking a dip in the same reservoir until they come across Welsh Water employee Gwyn Thomas who lists the risk swimmers face in the water.

Education Officer Claire Roberts, said: “When the weather is hot, cooling off in a reservoir may appeal to many, but the public must remember that automatic equipment located under the surface of the water can operate without warning.

“And, the very cold, deep water can cause even the strongest of swimmers to get into difficulty very easily.

“We know that people listen to our message to swim in safety and not in reservoirs, but we are appealing to parents particularly to make sure they know where their children are and to keep them from going into reservoirs.
